Nissan Repair: Altima suspension, nissan altima, left front tire

Question
Sir, My 2000 Nissan Altima seems to have a bounce in the front end when initially placed on the road.It seems that after warm up the car suspension will smooth out. The right front half shaft was bad and replaced, r/s ball joint boot was torn and replaced the joint. The front brakes were worn and replaced and rotors resurfaced. No significant change.
New tires were placed 6 months ago, and you can see a slight uneven wear in the left front tire (cupping). Could it be a balance and rotation problem? Vehicle does not pull to the sides while driving and brakes smooth.It has very minimal vibration on the road at any speed, problem at under 15 mph.Tire press. good,tie rod and idler good, no play.
This program has helped me in the past so here goes another for the experts.
Thank you

hello.  you never mentioned that you replace the struts.  i suggest to have all 4 struts replaced with new top mounts and have another alignment done.  a new set of tires will help too, if you havnet done so.  this should feel like a new ride with all those repairs.  the bill should be about 600 - 700 dollars, 250-300 for all 4 struts, 150 in mounts, 3-4 hours labor, + alignment.  good luck.
